TO ALL WHOM IT MAY-CONCERN Be it known that I, OLAuonDncnnUx, o the city, county, and State of New York, haveinvented a new and improved Wagon-Brake; and I do hereby declare that the following is a full, clear, 'end'exa'ct description thereof, which will enable others skilled in the art to make and use the some, reference being hedto thetacomnpanying drawings, forming part, of this speeification, in which'.-

Figure 1 represents a. plan or top view of myinvention. Figure 2 averticel transverse section of the same, the plane of section being indicated by the linexwfig. 1. Similar letters of reference indicate corresponding parts.

This invention relates to a new'wa gon-brake, whichcan be attached to all wagons, but which is inore'par ticularly intended as an attachment to the self-acting safetykdevice for carriages, for which Letters Patent No;

The invention consists in secnring adjustablering saround the hubsoi" the rear wheels, said rings having lugs projecting from their peripheries, and in having an 'oscillating bar hinged parallel to the rear axle, with projecting lugs at its ends, so-thatwhen the bar is turned hythe-forward motion of the brake-rod, pivotedto u. cra'nli on the bar, its lugs will strike" against the lugs on-the ring, and will the1'eby-prevent.the wheel from turning, thus stopping the carriage.

.The rings can he'adjusted more or less tightfaround the hubs, so that the wheels may either ,bebrought to adead stop, or maybe allowed some motion. when the brak'e is applied.

A represents the rear axle of a. wagon, carriage, or other vehicle. B B are the wheels. hung on the axle A in the ordinary oi suitable manner.

a a are the hubs of the wheels B. Around the inner ends of the hubs ore laid rings, 0 0; which either consist of one piece having lugs, b'b, at the ends, and held together by means of a screw or bolt, was shown in fig. 2, so that the ends *can'be screwed together to make tlierings fit. more or less tight around the hubs, or which consist of two or more pieces,-.connec ted together by 'means of bolts, screws, or their equivalents fitting through fiangesarrang'edat-the ends of' each "piece.

.D is a horizontal bar, having its hearings in blocksE E; which project from the'axle' A, or" from another fixed part of the wagon. I p

The ends of the bar l) are provided with projecting lugs 02 d, as shown, which are oppositetothe inner ends .of the hubs a;

e is a crank'projecting from the bar, and 'connectedwiththe brakeu'odf, as shownr As the brake-rod is in its neutral position, the'lugs'ol will be off the hubs, ns'in fig. 2,'but when the rod isdrawh forward thebar 'D will be turned, so that the lugs at stand againstthe hubs a,.as shown by red lines 'in fig. 1, and thus the lugs b strike against the lugs at, as showh. i

The carriage will thus be either totally stoppe d, or a certain degree of pressure will be brought to act upon' the hubs a, to give a required'm'o'tion; The pressure is more or less, accordingto the manner in which therings were adjusted on the hubs.

ihe rings revolve with the hubs as long as the-brake is not applied. One ring on one hub inaybe suflicien't although it is'best to stop'both wheels at once.-

Having thus described my invention, what I laimas new, and desire to secure by Letters Patent is Theadjustable rings 0 C 0nthehubs of the wagon-wheels, when provided with lugs bb, in combination with the oscillating-hair D, having lugs d, al'lpxranged'and operating substantially-asherein shown and described.
